What are potential long-term issues with PCP use?

Persistent cognitive problems is identified as a potential long-term issue with PCP use. PCP, or phencyclidine, is an anesthetic that can have significant psychoactive effects when abused. Long-term use of PCP can lead to neurocognitive deficits, affecting attention, memory, and executive function. Research indicates that individuals who misuse PCP may experience difficulties in learning new information, problem-solving, and maintaining focus, all of which can have a detrimental impact on daily functioning and quality of life.

The other choices suggest improvements or positive aspects that are inconsistent with the known effects of PCP. For instance, increased social skills, enhanced emotional stability, and improved memory retention are not typical outcomes associated with PCP use; rather, users often experience social withdrawal, emotional disturbances, and memory issues due to the drug's hallucinogenic and dissociative properties.
